(2x)^3 + 3((2x)^2)(3) + 3 (2x)(3^2) + 3^3 = 8(x^3) + 36(x^2) + 54x + 27
 (by cube formula i.e (a+b)^3= a^3 + 3(a^2)b + 3a(b^2) + b^3)

(2x+3)(2x+3)(2x+3)
First solve the start part:
2x+3*2x+3
4x^2+12x+9
The second part:
(4x^2+12x+9)*2x+3
8x^3+24x^2+18x+12x^2+36x+27
8x^3+36x^2+54x+27
This is the Answer.
